Senior Applied ML Engineer - LLM Routing (Remote-First)

Cast AI seeks an applied-ML platform engineer to own the routing model end to end—features, objective, training, calibration, and release cadence. You’ll build the evaluation that gates changes: production-parity benchmarks, router-vs-router comparisons, drift monitoring, with robust signals from live traffic. We value strong Python and SQL at scale, grounding decisions in production fleet data and benchmarking harnesses.
